-------------------------------------------------------------

Attaching a possible patch based on version CXF 2.1.4.0-fuse (which should be equivalent to Apache 2.1.4.0). 
Instead of introducing another wsdl2java option, this patch simply uses the -Xmx settings of wsdl2java itself and passes it on to javac as -J-Xmx option using this line of code:

argList.add("-J-Xmx" + Runtime.getRuntime().maxMemory());

So users can set -Xmx in the wsdl2java script and that setting will be propagated to the javac compiler as well. This should prevent OutOfMemoryErrors going forward.

> Running wsdl2java -compile will also kick off javac in order to compile the generated files. In case a large number of files got generated, the compilation might fail with an out of memory error. We could add another option that allows specifying a maximum heap size for the java compiler. Perhaps another -mx switch or so.
